No Java support found

No Java support found

Every time I restart Octave, the first time I run a program based on XLSREAD, I receive the warning:
Detected XLS interfaces: warning: No Java support found (no Java JRE? no Java pkg installed AND loaded?)If I run again the program, there is no more warning. I thought this was because I needed to expressly load the package Java. However, I've read in the updates, that the more recent versions of Octave no longer require to load Java. Am I missing something?

Re: No Java support found

Dear all,
I am writing because I found the same problem or similar with my Octave v
4.4.0 (Ubuntu 16.04.5 LTS)
I must say that I have a Matlab code (written by someone) and after running
it, it stops and says the following:
warning: fopen:
'/home/martin/Documentos/euge/vievs/COMPILE/VIE_MOD_V30/gpt3_5.grd' found by
searching load path

I am new in Octave and Matlab but Iam sure the problem just occurs only in
Octave. I saw the following entry https://savannah.gnu.org/bugs/?45914 and
it seems that the bug is still there.
I followed one of the instruction there and the same occurs
-----------
x = 0
>> save x x
>> unlink ("x"); sleep (10); fd = fopen ("x", "rb")
warning: fopen: '/home/martin/Documentos/euge/vievs/WORK/x' found by
searching load path
fd = -1
-----

Do you have any ideas on how to solve it?

Thanks in advance
Eugenia

Of course, I need to use the file gpt3_5.grd but I need to solve that
warning. Do you have any ideas?
